Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 08, 2023The c.838G>A (p.A280T) alteration is located in exon 6 (coding exon 5) of the RABGAP1 gene. This alteration results from a G to A substitution at nucleotide position 838, causing the alanine (A) at amino acid position 280 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
